HDL6M06522BN

Specialized ICS Overview

The HDL6M06522BN is a high-voltage analog switch IC featuring 32 single-pole single-throw (SPST) channels. It operates on a single +5V supply, eliminating the need for external high-voltage power rails. The device supports analog signal voltages from 0V to ±100V within a frequency range of 10kHz to 20MHz. Key electrical parameters include an 8Ω main switch on-resistance, 2A peak current capability per channel, and low charge injection of 10pC into a 1000pF load. It integrates active ground clamps, thermal protection, and a 32-bit serial shift register interface.

Specialized ICS Feature Summary

• 32-channel SPST analog switches with ±100V signal range and 8Ω on-resistance
• Single +5V operation without requiring high-voltage power supplies
• Low charge injection (10pC) and -60dB crosstalk performance
• Integrated 35Ω ground clamp switches and embedded thermal protection flag

Specialized ICS Applications

• Ultrasound imaging systems
• High-voltage signal routing in medical equipment
• Multi-channel data acquisition front-ends

Specialized ICS Procurement Notes

Verify the package marking code QN084-B-P-SD corresponds to the 84-QFN (10x10mm) variant. Confirm storage conditions require 5–35°C and 40–70% relative humidity. Ensure moisture sensitivity handling protocols are followed if the seal is broken, as reflow soldering profiles must adhere to JEDEC J-STD-020 standards to prevent package cracking.

Specialized ICS Selection Notes

Select this component when designing systems requiring high-voltage switching without complex bias generation. The 8Ω on-resistance and 2A peak current support robust signal transmission. Verify logic interface compatibility, as the device accepts 1.8V to 5V CMOS inputs while maintaining a separate +5V VDD supply. Consider the 84-pin footprint for PCB layout constraints.

Specialized ICS Part Context

This device belongs to ABLIC Inc.'s high-voltage analog switch family, specifically designed for ultrasound applications. It differs from lower-channel-count variants by integrating 32 independent paths in a single 84-lead QFN package. The unique pin-out arrangement facilitates easier PCB trace routing compared to standard multiplexer layouts.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult ABLIC Inc. directly for cross-reference information or verify pin-to-pin compatibility with other high-voltage analog switches if alternative sourcing is required.

Specialized ICS FAQ

Does the HDL6M06522BN require a negative voltage supply?

No, the device operates solely on a single +5V positive supply (VDD). It handles bipolar analog signals up to ±100V without needing a negative rail.

What is the function of the DS_ASW pin?

The DS_ASW pin controls the ground clamp switches. When High, it disables the 35Ω ground clamp; when Low, it allows the main switches and ground clamp switches to turn on and off alternately.

How is thermal protection indicated?

Thermal protection is indicated via the THP pin, which is an open-drain output. It activates when the junction temperature exceeds approximately 110°C, providing a flag for system monitoring.
